    The change of an individual serving as team leader is a frequent and disruptive event in organizations. Such changes might influence the behavior of both the newly appointed leader and the team. In soccer, there is a common expectation that a captain as a formal-transformational leader positively affects sporting performance. Despite this wide belief there is limited empirical evidence. We investigate the effects of exogeneous changes of a captain on the individual and the team’s effort and performance as well as outside observers’ evaluations. To test our hypotheses, we utilized individual soccer player data (N = 766) from 2,448 Bundesliga games during eight seasons (N = 48,263 player-game observations). We found that neither the newly appointed team captain nor the team itself showed higher objective effort or performance after the succession event. Nevertheless, experts rated the newly appointed team leader as demonstrating superior performance, indicating a potential leadership attribution bias.
